  • This book was absolutely amazing, I just recommended it for the fifth time. And every time I start a complex build I find myself running to it. Absolutely stellar.

  • I recently picked one of these up. There are a couple of gray areas in the instructions, and I threw a quick assembly video together and post that should help a little bit. It makes a nice accompaniment to the instructions:

    Blog post and video

    Hopefully it helps!

  • The price is fine. PCB + ATMega328P flashed + bits, pieces, packaging. Code created by Sparkfun. All adding up to a keyboard a kid could learn and put together for under 40 bucks? Its fine.

    Some people (such as below) expect you to challenge the market at China engineering costs and development. Yes, an ATMEGA328P can be grabbed for about 3.65 with no bootloader from China in small quantities. But local ATMega328P with something flashed? Your looking at 7 bucks or so.

    Reality is, the price will never be low enough for everyone :)

  • I recently bought ~220 Ding and Dent items - and I couldn’t be happier! If your curious and what to see what I got — check out my blog here :). I posted photos and all. Totally excited!! Thanks SparkFun.


  • Wow. I ordered 11 boards. All turned out to be protoboards, full size. Very cool thanks guys

  • I reflashed it this morning using an Uno, and this time the flashing worked: http://www.gammon.com.au/forum/?id=11635

    The redboard is finally responding. Still no response from spark fun - but at least its working.

  • It is a nice theory. However I have 3 other boards that have never exhibited the issue. Side-by-side, the red board fails and the official Uno works on two different computer systems on 1.0.1, 1.0.5 and 1.5.5 beta. I’m still waiting for support to reply to my emails. Unfortunately yes, in my case, it seems to be only one specific redboard.

    Also in the first 3 pages of the search you provided - only 1 entry matches the error and is unrelated as for me mine worked and gradually started failing over time.

  • I loved the board. But it only worked for about a month. It started saying Access Denied on occasion, and now it will not allow me to upload sketches at all. And has been in that state for a week. My advice, buy a true arduino.

  • tnx gr8 cideo comparison

  • you just know he hit the refresh button more than once too!

No public wish lists :(
